Figure 8.18 shows a system used to spray polluted water into the air to increase the water’s oxygen content and to cause volatile solvents in the water to vaporize. The pressure at point B just ahead of the nozzle must be 25.0 psig for proper nozzle performance. The pressure at point A (the pump inlet) is -3.50 psig. The volume flow rate is 0.50 ft3/s. The dynamic viscosity of the fluid is 4.0 × 10–5 lb•s/ft2. The specific gravity of the fluid is 1.026. Compute the power delivered by the pump to the fluid, considering friction energy loss in the discharge line.
